You are trying to throw your cofounder under the bus without going directly to him first? Tell him whats on your mind. At least you owe him that. At one point you picked him to be your cofounder and now maybe things are not working out, it might be his fault, maybe he is having issues or doesn't know he is not collaborating as much, but you owe him at least a direct conversation man to man. He will appreciate this more than being thrown under the bus.

again, I don't know the full details of your situation but there is two sides to a story. Whatever you end up doing won't be pretty but talking is and discussing things hombre a hombre is the best approach.
